The recent able investigation of the Hongkong Flora by Major Champion and Mr. Bentham has materially increased our knowledge of the intimate relationship between the Floras of China and the eastern parts of India; amongst many instances, we may select the repaarkable genus of Ferns, Bowringia*, found in Hongkong and in the Khasia moun- tains ; Wikstrcemia, a genus of Daphnes; Bucklandia, Enki- anthus, Henslovia, Scepa, Antide&ma, Benihamla, Gwigtda, Myrica, and very many others; in fact, there is scarcely a genus in the yholc Hongkong Flora that is not also Indian. Euryale ferox, which is wild in the Gangetic delta, and its found as far westward as Kashmir, is abundant in China; and Nepenthes phyllamphora, a native of the Khasia mountains, is also found at Macao, and eastward to the Louisiadc Archi- pelago. 4, The Siberian type.—This is characteristic of the colder temperate parts of Asia, and is very fully represented iu the upper temperate and alpine regions of the Himalaya, de- scending in the north-western and drier parts of the chain to very low levels. It approaches, in many respects, to the South European -vegetation, but is characterized by the pre- dominance of Fumariacea, PotentitttB, Leguminosa, especially Hedysarum and Astragale®, of Umbellifera, Lonicera, Arte- misia, Pedtcufaris, and Boraginea; and by the rarity or total absence of certain groups or genera .which are especially abundant in Europe, such as Cistace®, Rosa, Rubus, Trifolium, Erica, Ferns, and other cryptogams. As the Alps of Central Asia rise gradually from the elevated tracts of Southern Sibe- ria, and possess a very similar climate, the increasing elevation compensating for the diminution of latitude, a very Siberian * Jfotpriityw of Hooker, * Kew Journal of Botany/ vol. v, p. 2&f, A na»w superseded by the &<w>riqgia of Beuthain, in Hooker's *Kew Journal of Bo- tany/ vol. iv, p. 75.
